Problems solved by technology

The packing needs to be replaced regularly, the effective area is small, the duration is short, the control degree is limited, and the effect on gas pollution control is poor
[0005] 2. Ultrasonic technology, which uses the treatment device to generate electromagnetic waves or ultrasonic waves of a certain frequency to remove bacteria, dust and simple gas pollutants in the air, and has no obvious effect on the treatment of polluted gases
[0006] 3. Physical sealing technology, through brushing, spraying, soaking and other forms, the treatment product can be evenly covered on the surface of building materials, furniture, etc., forming a dense film, so that the pollutants in the material cannot be released into the air, and prevent harmful effects on the human body. Causes damage, but may cause secondary pollution, and the continuous effect is unstable
The duration is short, and individual treatment products have toxic side effects, which can easily cause secondary pollution

Abstract

The invention belongs to the technical field of air purification, and particularly relates to a biological enzyme air purifying agent as well as a preparation method and application thereof. The preparation method comprises: respectively dissolving specific enzyme species, extracting supernatants, mixing and compounding the supernatants, concentrating the mixture at a low temperature, and purifying the mixture to obtain an enzyme mixed solution; adding tea polyphenols, citric acid and an activator, stirring the components evenly, and then adding a specific microbial agent to prepare a biological enzyme air purifying agent. The biological enzyme air purifying agent can remove formaldehyde, benzene, xylene, TVOC and organic substances of other odor sources in the air for a long time throughdecomposition, and also has a sterilization effect, and the whole process is environment-friendly and nontoxic and does not produce secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a biological enzyme air purifier and its preparation method and application. Background technique [0002] With the rapid development of social economy and the continuous improvement of living standards, the accompanying environmental pollution is becoming more and more serious. In particular, indoor environmental pollution caused by decoration materials, furniture, tobacco, and home appliances has become a major killer affecting human health. Therefore, be badly in need of developing a kind of air purifier that has degrading volatile organic compound in the air and has no pollution and no side effect, to satisfy people's requirement to the air quality of the indoor places such as life, work. [0003] Technologies commonly used in the field of air purification today: [0004] 1. Physical adsorption technology, which uses physical adsorption to fix pollutant...
